Mikuni Jet Needle for VM Carburetors Jets

The Mikuni jet needle for VM series carburetors is a precision-machined metering needle. It controls fuel flow through the needle jet (also called the needle valve or metering jet) in the mid-range part of the throttle. Mikuni is a long-established maker of carburetors and tuning components for motorcycles, ATVs, snowmobiles, and other powersports and small-engine uses. The needle is designed to work with Mikuni VM round-slide carburetors.

Key Features:

• Tapered needle profile that meters fuel as the slide rises, which sets mid-range mixture
• Precision-machined for consistent fuel delivery and smooth throttle response
• Built for Mikuni VM series round-slide carburetors
• Clip-groove design lets you raise or lower the needle to fine-tune the air/fuel mixture
• Available in multiple needle profiles so you can match your jetting and tuning needs

Replacing a worn or bent jet needle can restore crisp throttle response and an accurate mixture. Swapping to a different needle profile is also a common way to tune a carburetor for modifications, altitude, or changes in weather. For best results, pair the needle with a matching needle jet and main jet, and set the clip position according to your jetting plan.
